' counting machines and more particularly to serial number controls forsuch machines for controllingserial numbering operations upon recordswhich pass in a run through the machine.

In certain forms of record controlled machines, serial numbering meanssuch as counting means, printing means and/or serial number punchingmeans are desirable for effecting serial numbering operations uponrecords. With such ma,-

chines, certain records in/ a run may have distinctive characteristicssignifying that they are leading records of a group, or otherdistinguishing characteristics may signify that a particular record in arun is misplaced or of some form which makes such records unsuitable forserial numbering operations. Furthermore, in machines of the aboveclass, provision may be made for rejecting any desired records out of arun of other records and in such event provision must be made so as notto count or serially number such rejected records, otherwise serialnumbers on following records in the run would be incorrect.

85 Accordingly, one object of the present invention resides in theprovision of a machine provided with devices for'the automaticelimination of improperly placed or marked records which are present ina run of records and for suppresscc ing serial numbering and/or serialpunching and/or serial counting of rejected records.

The present application constitutes a division of our copendingapplication Serial No. 662.250, filed March 23, 1933, Patent No.2,120,233, dated June 14, 1938, for Control means for record controlledaccounting machines.

While the present application is particularly directed to serialnumbering controls, such'controls are interrelated with the controls forthe accounting machine proper and such accounting machine will thereforebe herein fully described and explained.

Before describing the details of the various parts of both units of themachine, a general description will be given of the various units andtheir locations in the card handling, punching and entry receivingsection and in the calculating section. The card handling, punching "andentry receiving section embodies a card feed, card handling and punchingsection and a card reject section, which are shown in the upper righthand corner of Fig. 1a, and also shown in transverse cross-section inFig. 2 and in sideelevation in Fig. 3. This part of the machine isarranged to feed cards and derive readings therefrom and afterwards passthe cards into a punching mechanism where certain of the cards may bepunched. The punching mechanism is a punching mechanism of the gangpunch type wherein there is a preliminary selection of punches forpunching and a subsequent displacement of the selected punches throughthe card. The card handling section of the machine also includes anumber of accumulators or receiving devices enumerated as follows. Thereis a receiving device designated MP for-receiving the amount of themultiplier, a receiving device designated MC for receiving the amount ofthe muitiplicand and a serial number counter designated SR and areceiving device for receiving control number designated CN. These areshown on Fig. 1.

The calculating unit or section of the machine which is showndiagrammatically on the bottom of Figs. 1 and 1a, comprises the usualaccumulator for accumulating right hand components of partial products,which is designated RH and an LH accumulator for left hand components ofpartial products designated LH. These accumulators are shown on Fig. 1a.The calculating section of the machine also includes a multiplying relayunit generally designated MPH. (Fig. 1) and in this calculating sectionthere is also provided a column shift unit generally designated CS.Certain additional electro-mechani cal muiti-contact relays generallydesignated CR are also located in the CS section of the machine.

The card handling unit includes a number of cam contact devices and anemitter device which will be subsequently described.

In the calculating unit there are also cam contact devices and emitterdevices which will also be subsequently described.

Machine drive The card handling and entry receiving section of themachine is adapted to be driven by a constantly running motor Z (Fig.1), which mo tor, through a belt and pulley and ratchet drive drives ashaft 5i, which shaft drives an A. C.- D. 0. generator 52. The A. C. endof this generator produces alternating current impulses for actuatingvarious counter magnets and relay magnets and the generator also has aD. C. (direct current) takeoff section. Shaft Ii, through worm geardrive 5! drives a vertical shaft II. which shaft, through worm gearing55 is adapted to drive the main drive shaft 56. The MP, MC, SR and ONreceiving devices are driven from this drive shaft in the customarymanner. The reset drive is provided for in the following manner. Shaft56 is provided with a spur gear I1, driving a gear 5| with a four to onedrive ratio. Gear SI has extending from it four Geneva pins cooperatingwith the cross-element of the Geneva designated SI. Secured to 6| is aninternal gear 6i which has cooperating with it a spur gear 62 mounted onthe end of the reset-shaft 63. The various counters have the usualelectromagnetically controlled reset clutches. Shaft 56 extends to theright from the Geneva drive and is adapted to drive a gear 64 (Fig. 1a).This gear has a two to one drive to a gear 65 which is revolubly mountedon card feed drive shaft 66. Fixed to gear 65 is a notched element 51 ofa one revolution clutch which is provided with two notches and thecomplemental parts of this one revolution clutch including pawl El andpawl carrier 9 are fixed to shaft '6. The one revolution clutch isengaged by energization of a card feed clutch magnet ll. With the clutchengaged, shaft 66 will rotate and make one revolution while the maindrive shaft I makes two revolutions. "with the clutch disengaged, shaft66 will be stationary while shaft 56 will continue its rotationalmovement. Shaft 66 has fast to it a mutilated gear II (see Figs. 3 and3a) which drives a back gear train generally designated Ila (Fig. 3),which in turn drives a sleeve I2 revolubly mounted on shaft 66. Themutilated gear drive is generally similar to that shown in Fig. 8 ofLake U. S. Patent No. 1,757,123. Sleeve I2, through spiral gearinggenerally designated I3, drives the lower of a set of feed rolls I4(Fig. 2). Cooperating with the 7 lower feed rolls I4 are upper feedrolls .I4a of the usual construction which are preferably gear driven inunison with the lower feed rolls. Contact rolls I5 and I6 are alsoprovided which are driven by gearing extending to certain of the rollsI4a (see Fig. 2). Spiral gearing generally designated II drives lowerfeed rolls I6, 16b and 160. The upper feed rolls I60. may be positivelygear driven in unison with the lower rolls 16 and upper roll 1800 maylikewise bepositively gear ,driven in unison with the lower feed rolls160.

Upper feed roll IBbb preferably is frictionally driven from the lowerfeed roll 16b and the peripheral velocities of rolls th and 18b are suchthat the peripheral speed of these rolls is preferably slightly greaterthan the other rolls of the I6 set. This is for the purpose of urgingthe card into cooperation with the card stop in a manner to besubsequently explained. Increased peripheral speed maybe provided byproperly proportioning the relative size of the rolls or by properlyproportioning the gearing driving the lower roll 181;. This section ofthe machine is provided with a card supply magazine I9 and the usualdischarge hopper 80 (Fig. 2). A picker 8!, which is crank operated inthe usual manner is driven in any suitable manner from the drivingsleeve I2 as by the driving train 62 shown in Fig. 3. This section ofthe machine is provided with a set of advance sensing brushes 83 whichcooperate with the contact roll I5. A second set of sensing brushes 84cooperate with contact roll I6. Preferably the drive of rolls I5 and I6is such that these contact rolls slip slightly relatively to the card tocause a slight creep or slipping action of the card with respect to thecontact rolls. The usual card levers operating contacts 85 and 06 arealso provided which are adapted to be closed upon the passage of cardsthereunder and to open up upon the failure of a card to cooperate withthe respective card levers. Another card lever with associated contactsBI'is provided in the punching section of the machine. The arrangementof the card feed drive is such that with the one revolution clutchengaged, the shaft 66 will make a complete revolution during two machinecycles. Upon the first machine cycle and during the first half of arevolution of shaft 66 a card will be withdrawn from the supply magazineI9 and advanced to a point at which it is about to be sensed by thebrushes 83. The card remains in such position during the second halfrevolution of shaft 66 by reason of the mutilated gear drive II, Ila.Upon the re-clutching of the card feed the card which was previouslyadvanced to the point of cooperation with brushes 63 upon the first halfof the revolution of shaft 66 will be traversed past the brushes 83 to apoint at which the card is about to be read by the brushes 64. The firstcard will then remain in this position for the last half of therevolution of 66. Upon the following first half of revolution of shaft66, with the card feed clutch engaged, the card will be traversed pastthe sensing brushes l4 and will be picked up by the left hand pairofrolls I6 and 18a. and thereafter advanced by the right hand feed rolltrain which, it will be recalled, is driven directly from shaft 66through spiral gearing 11. After the card passes the brushes 64 and ispicked up by the first of the rolls I0 andl6a the driving relations aresuch that two machine cycles of shaft 56 and a corresponding singlerevolution of shaft 66 will produce a card feed, which in extent isdouble the previous card feed. A card on leaving the right hand pair ofrolls I4 and 14a and upon being picked up by the rolls I8 and 16a may betraversed into the punching die or to a reject station as will besubsequently described.

In further explanation of the driving relation of the various feed rollsit may be explained that in one counter cycle, 1. e. one revolution ofshaft 66, shaft 66 will make one half revolution. Such first halfrevolution of shaft 66 will impart through the mutilated and back geartrain II, Ila, one complete revolution to sleeve I2. One revolution ofsleeve I2 will produce rotation of rolls I4 and 14a to provide for acard travel from one sensing station to the next sensing station.

. On the right handend of the machine the driving relation of spiralgearing I1 is such that the first half revolution of 66 will produce anextent of card travel which corresponds in extent to that impartedbyrolls 14 and 14a in movin the card from one sensing'station to thenext sensing station and the second half revolution of 66 will produce alike additional extent of card travel.

The punching die comprises upper and lower die plates 92 and93. Sets ofrows of punches 94 are provided suitably supported for sliding movementin a punch operating frame generally designated 95. A series ofinterposer selector bars 96 are provided having ratchet teeth thereon,one interposer selector being provided for each row of punches and eachselector carrying on its end a punch operating plunger 91, which plungerslides over the tops of the punches 64 and under the top of the punchoperating frame 05.

The drive for the punching section of the machine is as follows.Referring again to Figs. la and 3, the shaft 56 is provided with a gear96 which in turn drives a gear 99 freely rotatable on a punch operatingdrive shaft I00. Gear 99 has fast to it the notched element ml of a onerevolution clutch. The complemental part of this clutch comprises a pawlI02 carried by an arm I03 which is fixed to the shaft I00. This onerevolution clutch is of the usual electromagnetically controlled typeand when engaged by theenergization of the clutch magnet 88 shaft I00 isturned through one complete revolution upon two complete revolutions ofthe main counter drive shaft 56. On account of the two to one drivingratio, the notched element IN is provided with two notches to receivethe pawl I02 in either of two positions. Shaft I00, near its right handend, through spiral gearing I04 (see also Fig. 3) drives cams rotatablymounted on a stub shaft I05. The gearing drives an inthe cross-bailmember I in any suitable manner as by spring pressed pawls III. Theinterposers are selectively positoned over the punches by means of pawlsII2 which engage the ratchet teeth in the top of the interposer bars inthe usual manner. Pawls II2 are electromagnetically tripped by punchselector magnets H3. After a given interposer or interposer bars havebeen selectively positioned under the control of the punch selectormagnets, the punches which are under the ends of the punch operatingplungers 01 will be positively forced through the card by the punchoperating cam I01 (Fig. 3), which cam, through its follower rocks a rockshaft II4, which in turn through arms and linkage III is adapted tooperate a suitable operating means for the punch frame 05, suchoperating means being here shown as a toggle Hi.

It will be understood that the cards will be picked one by one from themagazine I9 and in one machine cycle the first card will be passed to aposition in which the card is about to be read by the set of brushes 83.e card on a latter following machine cycle wil pass to the next readingstation to a position in which the card is about to be read by brushes04 and on following machine cycles, it will pass into the punching die.The card is arrested in the punching .die by a card stop I", which cardstop cooperates with the pivoted arm II8 (see Fig. 1a),

coacting with a cam II9 disposed on shaft 86 (see Fig. 3). With the cardstop Ill elevated, the card will be arrested in proper position in thepunching die. The feed roll 18b and cooperating roll llbb may be drivenso as to urge the card into cooperation with the card stop and after thecard has been intercepted by the card stop, slip relatively theretobefore their rotational movement terminates. Upon withdrawal of the cardstop after punching and upon resumption of card feed, the card will beejected from the punching die by the rolls 18b and I3bb and delivered bythe right hand rolls 18c and Nice to the discharge stack 00.

It will be understood that a card is removed from the die plates 92 and93 during a card feed cycle in which a new card is being advancedtowards the die and being sensed and that the one revolution card feedclutch permits a card to be advanced through one station and thenarrested for an indefinite number of cycles and that the one revolutionpunch clutch permits the punch to be called into operation after therequisite number of cycles. Upon the completion of punching, a new cardfeeding and reading cycle may ensue.

Serial number printing Provision is made in the present machine forimprinting a serial number on the card while the card is in the punchingdie. For this purpose a serial numbering printing head of conventionalconstruction and generally designated I20 (Fig. 2) is provided. Atypical printing head of this type is shown in United States patent toBates,

No. 789,113, dated May 2, 1905. This serial num- 1 her printing head iscarried on a pivoted arm I2I rotatably mounted on shaft I23 and springconnected to an arm I25 which is fast to shaft I23.

-A linkage I24 connects shaft I23 to the core of a solenoid I22. Uponenergization of the solenoid the shaft I23 is rocked to yieldingly drawdown the stamp head I 20 and imprint the serial number upon the card inthe die. Upon each imprinting operation the serial number is changed inthe usual manner.

means Card reject devices In certain operations of the present machineit is necesary that a card be removed from the run of cards before suchcard reaches the punching die. For this purpose a card reject box I21 isprovided (see Fig. 2) and a deflector vane I2! is provided which isadapted to be elevated up into the card path by energizing magnet I29.With I20 elevated, this deflector will be in the path of the cards andthe advancing card will be deflected into the reject magazine I21.Obviously any card which enters the reject box will not be advanced intothe punching die and will not receive a serial number imprint.

Emitters and cam contacts in card handling and entry section The maindrive shaft 56 is adapted to drive the cams of certain CC cam contactdevices, such cams being correspondingly designated on Fig. 1 as CC-I toCC-3 inclusive. Impulse distributors I34" and I34a are also provideddriven in unison with these cam contacts. The usual impulse emitters I35and I38 are also provided driven from the main drive shaft 56.

Upon a shaft driven with a one to one drive from the shaft 06 in thepunching section of the machine (see Fig. la) there are provided thecams of a number of FC cam contacts. Such cams are correspondinglydesignated FC-I to I9 inclusive on Figs. la and 3. The punch operatingdrive shaft I00 also drives the cams of a PC group of cam contacts. Suchcams are correspondingly designated on Figs. la and 3 as PC-I to 4inelusive.

Calculating section The calculating section is driven from its owndriving motor Z-2 and the drive from this motor is substantially thesame as the drive previously described for the parts in the cardhandling section. Corresponding parts will be given the same referencenumerals with the suffix b, that is the motor Z2 drives a shaft 5Ibwhich in turn drives a generator 52b. This generator 52b may beidentical with generator 52 with a 52AC section marked 52ACb and a 52DCsection marked 52DC-b. Shaft 5i b, through gearing 53b drives verticalshaft 54b, which through worm gearing 55b drives the calculating unitmain counter drive shaft 56 A similar Geneva drive 51 58 60 Bib and 62bis adapted to drive the calculating unit reset shaft 63b. The driveshaft 561) also extends to the left (see Fig. 1a) and through suitablegearing shown on Fig. 1 drives shaft 50c which in turn drives cams I31which cams are adapted to operate bell crank follower members I30 andslidably shift serrated operating bars I39 for the multi-contact relaydevices. The RH and LH accumulators are driven from the shaft 56b in theusual manner and selective reset is provided by the usualelectromagnetic one revolution clutches. The LH accumulator is providedwith reset contacts I40 (Fig. 1a) which contacts are arranged to beclosed upon the reset of the LH accumulator.

In the calculating unit there are certain CL cam contacts which aredesignated CL-I and CL-Z and such cams are driven from the 56b shaft inthe usual manner. The calculating unit is also provided with twoemitters HI and I42 which are also driven from the shaft 50b.

The receiving devices and accumulators which are used in both the cardhandling entry receiving section of the machine and the calculating Isection of the machine are of the usual type as be described.

segment customarily used in tabulating machines and such accumulatorsare provided with the usual electromagnetically actuated clutches. Thevarious accumulators and receiving devices have commutator type ofreadout devices which will now MP readout Figs. 6 and 7 show the readoutdevices MPRO for the MP counter. In Fig. 6, I48 is a clutch gearpertaining to the units order of the MP (multiplier) receiving device.Gear I is driven from this clutch gear and this gear in turn drives twobrush assemblages, one designated U, which traverses a set of segmentsI46 and also a current supply segment I41. There is another brushassemblage 1U driven by gear I, the brush of which traverses a segmentgenerally designated I48 and which segment is provided with a singleconducting spot at the zero position. The brush 1U also traverses acommon supply I48. There is a similar brush 1T which is positioned fromthe tens .order clutch wheel I56 and which also traverses the segmentI88 which contains only the single conducting spot at the zero position.Brush INT also traverses a separate common current supply segment I5I.Similarly thereis a brush MET driven in unison with brush It?! and whichbrush I861 traverses the segment spots I52 and which receives currentfrom the common current supply segment I53. This arrangement of brushesand segments is repeated for the higher orders in the MP readout device,i. e. each alternative segment is like I48 with only a zero spot in thezero position. Alternating with these segments are alternating segmentssimilar to I46 and I52 with a multiplicity of spots on each segment.

The detailed construction of this readout with its brusheassemblage,segments, etc. is shown in the cross-sectional view Fig. '1.

The wiring of the readout will be shown in connection with the circuitdiagram.

MC readout Referring now to Figs. 8 and 9, in Fig. 8'is shown the brushdriving arrangement for the MC readout. With this readout the unitsclutch train I54 drives a units brush assemblage I 55U which cooperateswith a set of segments I56 and which brush receives current from acommon conductor segment I51. Similarly the units driving train I54drives a brush assemblage I55T receiving current from a conductorsegment I58 and cooperating with segment spots I59. Also cooperatingwith the segment spots I59 is another brush assemblage I60T receivingcurrent from a conductor segment I6I and which brush is driven from thetens order clutch train I62.

This arrangement is repeated for relatively higher orders.

Fig. 9 shows the detailed mechanical construction.

RH, LH, SR and UN readouts With a readout mechanism of 1 I68. Brush I65on the other hand is driven from the tens order clutch train I69. Asimilar arrangement of brushes and readout spots is provided for therelatively higher orders for these accumulators and counters and thewiring of these readouts is shown on the circuit diagram. In Fig. 10,nine segment spots I63 are shown. This arrangement is for the RHROdevice only. The LHRO, the SRRO and the CNRO all have ten segment spots.

\ Fig. 11 shows the mechanical details of construction.

Multiplying panel and columm shift controlling relays The calculatingsection of the machine is provided with electromagnetically controlledand mechanically positioned and restored multi-contact relays. Theserelays are mounted on verti cal plates I which are suitably carried inslots in the frame part of the machine. Carried on each plate is amagnet which will be designated CS when the relay is to be used forcolumn shift purposes and XI, X-2, X-3, etc. when the relay is to beused for multiplier selection purposes and CR when the relay is to beused for simple multiple circuit control purposes. Such magnets whenenergized serve to control the establishment or breaking of circuits atthe multi-contact points of the relay. Each plate I16 has mounted uponit multi-contacts generally designated HI and I12. Contacts I12 havefastened thereto a strip of insulating material I13 carrying an L shapedmember I14, which member engages into the downwardly extending serratednotches on the serrated bar I89. Member I16 also carries a bracket I15having pivotally mounted thereon a latch member I16. The latch memberhas slight limited rocking movement between limiting stop pins and isnormally urged clockwise by a spring I11. A part of the latch member I16cooperates with a latch piece I19 fixed to a pivotally mounted armatureI 80. I80 also has a tail portion I8I arranged in cooperative relationto a restoring abutment I82 fixed and depending from the serratedoperating bar. With the parts in the position of Fig. 5, a cam I31 hasshifted its follower I38 and the operating bar I39 to a position inwhich contacts HI and I12 are kept open and to a position in which thestrain is removed between the latch I16 and the latch point I19 of thearmature assemblage. Therelay magnet may now be energized causing latchportion I19 to be lowered and allowing latch I16 to trip over the top ofthe latch point. Thereafter upon further rotational movement of cam I31,the bar I39 moves to the left and allows contacts I12 and I" to closeunder their own spring action. If a set of multi-contacts have beentripped and closed the operating cycle of the machine ensues andultimately the cam I31 again shifts its follower, causing the bar I39.to take a sufficient movement to the right to cause the armatureknockoff bracket I82 to intercept I8I and knock off any previouslyattracted armature. Subsequent movement of the parts allows the serratedbar to move back to the Fig. 5 position. If a magnet be not energized,its corresponding armature will not be attracted and the latch memberI19 will then prevent a closure of contacts "I and I12. 1

In the subsequent description of the wiring diagram the multi-contactswhich have been generally designated HI and I12 in the mechanical!!!description will be given designating reference numerals related totheir associated control magnets. Thus l-CRI to I! will designate theseventeen contacts controlled by the magnet l-CR, etc.

Before describing the circuit diagram, it may be explained that themachine is adapted for functioning under various operating conditionsand with cards perforated in various manners and variously arranged ingroups. Accordingly, a

. brief resume will be given first of the various operating conditionsand the different arrangements of cards for the different operatingconditions.

First condition.0perating under the first condition, the cards will bearranged in groups. The first card of a group will contain a multiplieramount and a control number only, but no multiplicand amount will appearon such first or leading card of a group. The detail cards of the firstgroup will contain multiplicand amounts and control numbers only.Following the first group, the leading card of the following group willcontain a new multiplier amount and a new control number, but nomultiplicand amount. The other cards of the second group will be detailcards, each containing a control number and a multiplicand amount.Operating under this condition the machine multiplies the multiplicandsderived from each of the detail cards of a group by the multiplieramount derived from the leading card of the group and upon encounteringa card with anew multiplier and with a change in control number themachine takes in the new multiplier amount and the new control numberand proceeds with the computation on the following detail cards of thatgroup. If the control number changes on a detail card, such erroneous ormisplaced detail card will be automatically rejected.

When operating under condition one, punching is suppressed on theleading card of a group and if serial number printing is being effectedprovision is made for suppressing serial number printing on the leadingcard of such group. Entries into the serial number, counter are alsosuppressed for the leading cards of a group. In short, the serialnumbering means is operative for the detail cards only. When a misplaceddetail card is rejected there is no entry of serial number or serialnumber printing, such operations being automatically suppressed.

Second condition.When operating under this second condition the firstcard of each group will have perforated thereon the amount of themultiplier, the amount of the multiplicand and the control number andthe detail cards of each group will have perforated thereon the amountof the multi plicand and the control number but no multiplier amount.Operating under this condition the machine is arranged to automaticallyreject a card if the control number changes upon a detail card whichcontains no multiplier amount. However, if the control number changes ona card containing a multiplier amount the machine automatically takes inthe new multiplier and a new control number and proceeds with thecomputation upon the first card of the group and upon the followingcards of the same group. When operating under condition two, computingresult punching and serialing operations are performed upon the firstcard of the group as well as upon the detail cards and accordinglyserial number printing and punching may be effected on all cards exceptmisplaced detail cards.

Third condition.0perating under this condition the cards will still bearranged in groups, each.

s eaves group containing a leadingcard containing a multiplier amountonly. The following cards of each group will be detail cards containingmultiplicand amounts only. Operating under this condition upon the firstcard of a group passing into the machine the multiplier amount appearingthereon will be taken in by the machine; This multiplier will be used tomultiply all of the multiplicand or detail cards of that group and uponthe entrance of anew multiplier card, the old multiplier would becleared out and a new multiplier taken in and such new multiplier wouldbe used to multiply all the multiplicand amounts on the following detailcards of the group. Operating under this condition it is unnecessary toprovide for the elimination of misplaced detail cards. Operating underthis condition punching and serial numbering operations may besuppressed on the first card of each group and there is no serial numberentry for the first card of each group.

Fourth condition.-Under this kind of machine operation each cardcontains a multiplier amount which also serves as a control number. Theleading card of the group contains a multiplier amount only. Thefollowing detail cards of the group contain both multiplier andmultiplicand amounts. Operating under this condition, the multiplieramount is intended to be the same for all the cards of a run, but if acard with a different multiplier is present in the run, such card willbe automatically rejected and the machine will proceed with theoperation on the following cards. If a card enters the machine with anew multiplier amount only appearing thereon, it indicates to themachine that the old multiplier is to be cleared out and a newmultiplier taken in and set up as a control number for the followingcards. Operating under this condition result punching is suppressed onthe leading card which contains a multiplier amount only. Serial numberentry andserial number printing are also suppressed for such leadingcards.

Fifth condition.-Condition five is substantially similar to conditionfour above set forth, but the leading card of each group is punched witha. perforation at either of the 11th or 12th index point positions todesignate that this card is the first card of a group. Under thiscondition this extra punching indicates that a new multiplier amount isto be taken in and as in condition four, if the multiplier derived fromany detail card does not compare with the multiplier derived from theleading card the card is automatically rejected. The punching and serialnumbering controls are the same as with condition four.

Sixth condition.0perat.ing under condition six, each card contains acontrol number, a multiplier amount and a multiplicand amount. 0peratingunder this condition if the control number on any card does not comparewith the control number derived from the first card of the run theerroneous or misplaced card will be automaticallyrejected. Serial numberprinting and product punching is effected on all computed cards, but ofcourse is suppressed on the rejected cards.

Seventh condition-In operating under condition number seven, controlnumbers do not appear on the cards, each card containing a multiplierand multiplicand amount. Result punching and serialling are effected forall cards.

A'plug connection is also made from one of the sockets 228to plug socket 229 which is wired to cam contacts FC-2. Each of thebrushes 84 at the second reading station is wired individually to a plugsocket 230. From the plug sockets 230, which pertain to the multiplierfield of the card, plug connections are made to sockets 23! which arerespectively wired to the 232MP magnets. From the sockets 230, whichpertain to the multiplicand field of the card, plug connections are madeto the 233 sockets which are wired to the 232MC magnets.

Automatic control unit. Before describing further operations; the*automatic control unit will be briefly 'des cribedlsee'f Fig. 12a). Thepurpose of this control" unit is to compare the control member whichread from a card with a previously enteredcontrolnumber. In describingthe automatic" control unit it will be assumed that the control"numberis already in the CN receiving device and that the brushes of theCNRO readout are positionedln accordance with such entered controlnumber. As a card passes the second set of sensing brushes 84, thebrushes 84 which pertain'tojjthe fcontrol" number held of th card will,through the plug connections at plug board 234 and t ipmgponnections atplug board 236, cause an en'ergiz'ation of the pick-up coils 231.

Operation The operations under condition one. willrbe first describedwith the assumption-that:Qthere contacts Dl now closed. cam contactsI'C-l to the other side 22' of the DC line. A card feed cycle now ensuesand the first card will be withdrawn from the magazine and advanced to apoint where the nine index point position of the first card will beabout to be sensed by the brushes It. The start key is now depressed asecond time or alternatively it may be maintained depressed to initiatea second card handling cycle to carry the first card past the brushes I3and to a position in which the perforations of the first card are aboutto be sensed by the brushes II. This card feeding operation carries thesecond card of the run or first detail card to the first sensingposition adjacent brushes It. When the first card approaches the firstsensing station, card lever contacts '8 (Figs. 2 and 12b) become closedcausing energization of relay coil B. The energization of relay coil Bcloses relay contacts B-l to provide a stick circuit for relay coil Athrough the stop key contacts 25! and relay contacts A-l. Under thenumber one type of operation the first card'of a group will contain thecontrol number and the amount of the multiplier. As the leading cardwith the control number amount and the multiplier amount thereon passesthe brushes II, the presence of a perforation in the multiplier fieldwill cause the establishment oi a brush circuit through the brusheswhich are wired to plug sockets 221 and thus energize relay coil E. The

circuit is from the 222 side of the AC line, through relay contacts B2(closed by the energizationof relay-coil B), through impulse distributorI34, contact roll Ii, sockets 220 pertaining to the MP field. sockets221, through relay coil E, through a plug connection from a socket 228to 229 and back through cam contacts FC-2 which are closed during thesensing of the multiplier field of the card from index point 8 through Iand back to ground,"through normally closed relay contacts L-2. Theenergization of relay coil E in this manner thus signifies that the cardwhich has been sensed, contains a multiplier amount.

The energization of relay coil E closes relay contacts El (Fig. 12b) toefi'ect energization of relay coil 1''. Energization of relay coil 1''closes stick contacts F--|, a stick circuit being established backthrough cam contacts FC--- which are cloud at this time. After relaycoil F has become energized and late in the cycle in which 1" isenergized, cam contacts FC-i become closed to eiiect energization ofrelay coil G. Relay coil G is a holding relay coil which may bemaintained energized after F becomes de-energized. The holding circuitfor G is through relay contacts G-l and cam contacts lC-I. Directlyafter the energization of relay coil G, cam contacts FO -5 open toeffect de-energization of I" by breaking the holding circuit therefor.It may be explained that relay coil G is energized at the time that thefirst card is about to traverse the brushes .4 (Fig. 2) provided thefirst card contains a multiplier amount.

The machine is now ready for a further card ieed cycle and during thisfurther card feed cycle the control number is entered into the CNreceiving device and the amount of the multiplier is entered into the MPreceiving device. This following card feed cycle is initiated in thefollowing manner. The start key is now depressed a third time oralternatively it may be maintained depressed until the leading cardapproaches brushes II and card lever contacts Ii (Figs. 2 and i2) becomeclosed, causing relay coil C to become energized. The energization ofrelay coil C closes relay contacts C--l to maintain the stick circuitfor relay coil A which in turn controls the energization of card feedclutch magnet II. It will be understood that as long as cards arepassing relay coil A will be maintained energized provided eithercontacts C-l or B-l are closed The entry circuits for the introductionof the control number and the multiplier will now be traced.

The energization of relay coil G in the manner previously explained willhave shifted relay contacts G-2 and G3l0 (Fig. 12a) to the reverseposition from that shown. Current supply is afi'orded from the 222 sideof the AC line through relay contacts C-2 now closed, cam contacts FC-Ito the impulse distributor lull, to contact roll 18 and via plugconnections from the sockets 230 pertaining to the MP field to sockets23l and thence through the 232M? counter magnets and back to groundthrough the now shifted G--2 contacts. The control number entry circuitsare from the brushes at the control field and sockets 2", via plugconnections to sockets 234 via the shifted GS-il contacts to plug board2" and through the plug connections at this plug board to the 232CNmagnets and back to ground.

The above described operations will haveentered the amount of themultiplier from the leading card into the MP counter and the amount ofthe control number from the leading card into the CN receiving device.

After the entries have been made in the MP and CN counters, cam contactsFC-S close to transfer the relay control action from the G relay to theH relay for controlling following operations. Upon the energization of Ha stick circuit is established through relay contacts H-i and PC-l (Fig.12b). Following the energization of H, relay coil G becomes de-energizeddue to the opening up of cam contacts FC-'l.

After the control number and the multiplier amount have been read fromthe leading card the card advances in the feed roll train II and Ila andthe leading card is advanced into the punching die. Upon the leadingcard reaching the punching die contacts I! close energizing relay coilD. With D energized contacts D-| open to prevent further card feed whenFCI close. During the feed of the leading card the deflector vane I28will be in the position shown out of the path of the card run andaccordingly the leading card will not be deflected. The energization ofrelay coil H will have closed relay contacts H-l (Fig. 12b) and withthese contacts closed a circuit is established from the AC bus 225 inthe calculating unit (Fig. 12d), via wire 252, over through switch H2 inthe position shown, through relay contacts H-l, through cam contactsFC-li which close at the proper time in the cycle and back through wireto the 254LH reset magnet in the calculating unit. The LH accumulator isnow reset. Reset of the LH accumulator closes the Ill reset contacts(Fig. 120) and energizes relay coil M to set up the cycle controller.Upon the energization of relay coil M it is maintained energized by theclosure of stick contacts M-l which establish a stick circuit throughcontacts l-CR-ll now closed. Under this type of operation which is beingdescribed, the leading card contains no multiplicand
